Some time ago my sisters iPhone 5s was stolen. Her provider didn't cover a replacement for some reason and she couldn't afford a new iPhone herself. So she decided to get something cheaper. And that was the Samsung Galaxy S4. She liked it the first few weeks. But then, she completely regretted it. I've seen her many times smashing it to the table because of crashes, slowness and other issues. She hates the device. I mean, it's not new to me that Samsung users hate the device they use. But seeing my sister this desperate to get back to iPhone, that's something.
And yes, she has just ordered herself an iPhone 6. So she will enjoy the incredible performance without any lag, it works together with her MacBook Pro thanks to Continuity, and she will get the latest updates once they are out. I feel happy for her.
You know, she promised me we are going to destroy that Galaxy S4 once she has that iPhone 6. Really looking forward to that! Can't wait to kick that piece of junk.
